We were approached by a famous superyacht tender manufacturer to see if we could put together a water tank package for them that included a pump, calorifier, accumulator tank and all the mounting points for each piece of equipment.
The resulting hot water was required for a small hand basin and a bathing platform shower head.
This little project may give you some ideas on how to save some space on your boat when specifying a Tek Tank for your refit, repair or new build.
This system would work just as well in any recreational or expedition vehicle as well as a welfare van.
